I ran across this in another context, and wondered how many Roon problems this might have caused.
Macbooks use a Wi-Fi interface called AWDL (Apple Wireless Direct Link) for features like AirDrop and AirPlay. Having AWDL on may cause your Wi-Fi connection to periodically reset. Although these issues can manifest in various ways, the underlying issue is the same: throughput and speeds drop, devices get disconnected randomly, and fail to rejoin the network.
